ES failed breakout?

ES filled the gap at 3843. It tried to go up to the next level but failed. 3843acted as an important price level for 2 days. Today after failed attempts to maintain above it, the market pulled back, hit it, and turned down. The market is getting closed to the lower edge of the channel (or a wedge, depending on how you view it) not a good place to short but overall momentum is down. 3800 as a whole number support may work but expect down or TR. Sell at EMA, or previous support level. It seems 3800 has been broken after 4pm, so 3800=resistance? Instead, 3750 -3735 = support.
